2017 Mercedes Benz W205 Thermostat Removal (read description)

This is not a tutorial or a how to video, I just wanted to post some of the footage I recorded for reference, It is time consuming and requires a good mental picture of all the parts and screws removed, having the right tools will make it easy, but regardless it will take time, It took me about 6 hours, I took my time. Please like or dislike the video, also check out my other mercedes videos

said it is not a tutorial. it is actually the best w205 thermostat tutorial that exists.

I'm glad you like the video

Thanks for deep and thorough insight to replacing the thermostat... I may don't Habs the time... I'll have to take it to a shop.

[@Critycal1]

@MontoyaFreightServiceLLC I did because I like working on cars, also had the space to do it, I was fun, and a learning experience as well

메르세데츠 벤츠..진짜 극악의 정비성이로군요..서모스탯 하나 교환하기 위해 저런 작업을 해야 하다니...제 차도 작업해야 하는데 큰 도움이 됩니다. 감사합니다.

[@Critycal1]

yes its too much work, hope it helps

[@mariog5598]

waooo this is what I was looking for, this a gem, should not save it but download it. THANKS for your video, now I can clean my throttle body.

[@spontekk]

Wow nice ! reminding myself never to buy this model benz !

[@Critycal1]

I did the best I could, glad you like the video

[@amarmatloob9624]

Hi, is this the same for the 2L petrol hybrid

[@Critycal1]

Not sure, but I looked up the part, and it shows the same part

[@cieumeo]

Im doing half way at the moment and t hinking do i need to take manifold out or not and I see your video. Thank you so much.

[@Critycal1]

intake manifold come out too

[@peterbigler1241]

Thank you for video doing mine this week. Was that 6 hours total or just removal? My GLC only has 55k miles, I am a little disapointed therm did not last longer.

[@Critycal1]

I took about 7 hours

[@dannyhedges831]

I just did the same process as in the video, except that I did not disconnect the battery and now when I start the car I get several collision assist errors and it does not go above 1500 RPM. Do you know what it could be? thanks a lot in advance.

[@Critycal1]

@dannyhedges831 I also did not disconnect the battery, nor the ECU that is next to intercooler, not sure what it could be

[@DIYMan-e6c]

I just replaced my C300 2017 thermostat, but didn’t change the manifold gasket. The car won’t start and I have two error codes. P0193 and P0108 along with a few throttle valve codes. Any idea what could have I missed?

[@Critycal1]

There is a couple of small connectors that I also missed under intercooler, also if the gasket is good you should be OK

[@timmo5443]

Hi I need to replace my coolant sensor on the same model, any ideas where this is pelase and what do I need to take apart? thanks

[@Critycal1]

Not sure about the location, but I do remember seeing about 4 plugs for sensors while replacing the thermostat

[@anishag6861]

Hello, thank you for making this video it has been extremely helpful! I just wanted to ask if your able to assist in where the connectors go back into the intake manifold Thank you!

[@Critycal1]

I had trouble remembering, the way I did it was to place parts back in and to see where the harness went and what connector was close to a plug, that's how I did it, but to specifically tell you, I can't. Also the connectors and plugs are different

[@anishag6861]

@@Critycal1 yep I’ve taken a picture of a few of where they go however missed out a few. I will go back and try to figure it out with how you’ve said! Thank you very much for your reply ☺️

[@anishag6861]

@@Critycal1 I will do 🤞

[@SEJason817]

Thanks for the video, its helpful for me ! But may i know if i already fix it, do i need to use the benz factory obd to clear the P012800 code ? Or every obd device can do it ? Thanks !

[@Critycal1]

It will clear on it's own, if it does not clear, a scanner will clear it

[@JoseMiguelL]

Do you know where is the Coolant Temperature sensor on a 2016 GLC300 located? Thanks

[@Critycal1]

I did a quick Google search and found it, I can not post links

[@che881]

Thanks

[@kgpax]

Thanks for the video, approximately how long did it take you to do that?

[@Critycal1]

It took me about 7 hours, because with a couple of breaks, but if I have to replace it again I say less than 3, because I know what to do

[@kgpax]

@@Critycal1 awesome thanks!

[@Critycal1]

@@kgpax the check engine light came on when it failed, scanned for codes and it called for the thermostat, after replacing it, I did not reset the light, the car itself cleared the code or check engine light

[@kgpax]

@@Critycal1 cool...that's the way it should be...some cars it's a nightmare to clear codes once the issue is fixed

[@MD-vf7rs]

@@Critycal1 may i ask what was the code u had?

[@johnindries4606]

omg ! all this work for a thermostat replacement ! it is ridiculous !

[@Critycal1]

Yeah man, stealership would be thousands, it took me a good 7 hours taking my time keeping a mental picture of every nut and bolt, if I need to replace it again, I say a good 3 hours

[@RowBoat-s5s]

Damn. I thought I checked everything before I bought mine, to make sure basic maintenance was relatively easy. Just thought of the thermostat. Came to see how it's done aaaaaaand I should not have bought this car. 😂 The WHOLE intake manifold?! 💀 Not looking forward to doing this. That's a lot of broken seals for a fugin thermostat. Ridiculous.

[@Critycal1]

Agree

[@RowBoat-s5s]

@@Critycal1 Sure is fun to drive though. Also very economical for the power output. It seems like it burns mostly air.

[@Maybaby1959]

I mean Mercedes has fell to shit every thing on mine died at 60 k thermostats esp crankcase Mercedes is sht now

[@Critycal1]

My C300 also needed the thermostat replaced at around 60k. Now it has 80k and needs more maintenance.
